专题10名词性从句名词性从句包括主语从句、宾语从句、同位语从句和表语从句。
考查的要点主要是连接代词和副词的正确使用、主语、谓语的语序、双重连接词以及特殊句型的使用等。
具体来说主要包括：1、考查名词性从句的连接词。
如：有词义的连接代词：who, whose, whom, what, which；连接副词：when, where, why, how；从属连词：that, whether, if, as if；无词义that在从句中不担任成分，有时可省略。
2、考查名词性从句的语序和时态。
3、考查it作形式主语、形式宾语的情况。
如：（1）It+be+形容词(necessary, important, obvious等)+that从句;（2）It+be+过去分词+that从句;（3）It+be+名词(a surprise, a fact, a shame,a honor等)+that从句;（4）It+不及物动词(appear, happen等)+that分句。
4、名词性从句中的虚拟语气。
如：（1）It is (was)+ essential,（important, natural..）+that…；（2）It is (was)suggested（demanded, wished, desired….）that…等。
5、what引导名词性从句时的语义功能和语法功能。
如：what=the thing that/anything that…；what=the place that…；what=the time that…；what=the person that…等。
6、whoever、whatever、whichever引导名词性从句时的语义功能和语法功能。
2017年将重点考查连接词that、what的用法；特殊疑问词引导的名词性从句；whever 引导的名词性从句。

二、宾语从句在复合句中作宾语的名词性从句是宾语从句，通常放在主句谓语动词 (及物动词)或介词之后。

【注意】下列形容词后常跟that引导的从句作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content等。
(有时也将此类词后的that 从句看作原因状语从句。
